Benefits of technology

The patent describes an electrically powered head restraint assembly for vehicles that can be folded up or down. The assembly includes a post assembly with a cross member section that connects two post sections. A head restraint bun is attached to the post assembly and a support structure is positioned inside the bun with the cross member mounted in it. The assembly also has an electrically powered drive mechanism that includes gears and an electric motor. The drive mechanism can move the bun to a folded or upright position. The assembly reduces chuck and is advantageously powered.

Problems solved by technology

Although the positioning mechanism work reasonably well, some head restraint positioning mechanisms occasionally experience “chuck” which is a noise produced by moveable component vibrating and contacting each other.

Abstract

A head restraint assembly includes a post assembly which has a first post section, a second post section, and a cross member section connecting the first post section and the second post section. The first post section and the second post section are adapted to engage a vehicle seat. The head restraint includes a bun moveably attached to the post assembly, a first gear, and a motor that rotates the first gear in a clockwise or counter-clockwise direction. Rotation of the first gear drives a second gear which drives a third gear. Rotation of the second gear in a first direction causes movement of the bun to a tilted position while movement of the second gear in a second direction causes movement of the bun to an upright position.

Description

FIELD OF THE INVENTION[0001]In at least one aspect, the present invention relates to systems for moving a head restraint between an upright and a tilted position.BACKGROUND[0002]Competitive pressure places a persistent demand on automobile manufacturers and suppliers to improve aesthetics and functionality of vehicle components. Head restraints are automobile interior components having the important function of providing support for a vehicle occupant's head during an accident.[0003]In the many vehicular head restraint assemblies, a bun is moveably attached to a vehicle seat by one or more posts. Characteristically, head restraints are positionable in either an upright or folded position. In the typical head restraint, such positioning is manually accomplished by a vehicle occupant. Although the positioning mechanism work reasonably well, some head restraint positioning mechanisms occasionally experience “chuck” which is a noise produced by moveable component vibrating and contactin...
